I've seen this issue everywhere online, from people on PC and consoles, all over the world - this is definitely not the problem of individual people's internet, not when the issue is so widespread (one or two maybe, but not thousands, just check out how many threads there are on this one topic just on this forum's support pages, there is one on the 'looking into' section of over 200 pages!). If it were an ISP thing, there would be loads of people offering a working solution, but nothing people have tried has seemed to make it stop. Basically, there are hundreds of threads about this one issue with no answers in sight

I thought yesterday's maintenance would fix it, but it seems to have made it worse as now I'm getting thrown out every few minutes instead of every 30 mins or longer. Just now was the last straw - got thrown out at the end of a long single player duty for my level 60 class quest and there is no way I'm going back in for fear of 90002 error - also means I can't do the dungeons .

It's looking like I'm gonna have to give up on doing anything significant on this game until it's fixed which sucks coz I was planning on doing an eternal bond in the next few weeks - no way the server is gonna hold for that length of time!

I've been playing the game for over 6 months with no previous error - seems to have been since 3.05 was installed :S my husband is also playing on PS4 and gets d/c'd.

Please fix this squeenix, I love playing this game too much to give it up now!
